### Internal Access

The ML100 can be opened by the user. This does not void the warranty, however, any damage caused by doing so will not be covered.

1. Ensure your body is discharged of any static electricity by touching a grounded metal surface.
2. Remove the 4x phillips screws on the outside of the case.
3. Use the tab for leverage to pull the bottom panel off

### Motherboard

Technical information related to the system's motherboard can be found from the support link below.

As of 12/2025, all ML100G-53s will be shipping with either I225s or I226s NICs.  This will be true until we run out of stock of the I225 motherboards

### Clear CMOS <a href="#clear-the-cmos-4" id="clear-the-cmos-4"></a>

Disconnect the system from all wire connections (power, ethernet, video, etc), then:

● Locate the clear CMOS jumper\
● Move the jumper over by 1 pin\
● Wait 30 seconds\
● Restore the jumper to its original position\
● Close up and power on the system. It may power cycle several times before it begins working again.

### Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

For increased reliability it is recommended to disable the Core Performance Boost BIOS setting. To disable the setting, navigate to:\
Advanced -> CPU Configuration -> Core Performance Boost -> Set to “Disabled”

Press F10 to Save & Exit.

***\*\*\*Please note that the AMD CPU’s Core Performance Boost (similar to Intel’s TurboBoost) is disabled on this series in order to maintain thermal performance in line with the expected operating temperature.\*\*\****

### Auto Power On <a href="#enable-auto-power-on-5" id="enable-auto-power-on-5"></a>

The auto power on feature will automatically turn the ML100 back on after DC power is lost and restored. To enable it, a jumper needs to be moved inside the unit. The ML100 can be opened by the user. This does not void the warranty, however, any damage caused by doing so will not be covered.

* Ensure your body is discharged of any static electricity by touching a grounded metal surface.
* Remove the 4x phillips screws on the outside of the case.
* Use the tab for leverage to pull the bottom panel off

* Remove the two screws from the USB board and gently lift it out of the way, leaving it plugged in.

<figure><img src="/files/VwX8SKyOwHEasTtQklDH" alt="" width="563"><figcaption></figcaption></figure>

* Remove the blue jumper circled at the top and place it on the 2 pins circled in the bottom left.
* Note: We are borrowing the clear CMOS jumper for this procedure. If CMOS needs to be cleared at a later date, keep that in mind.
* Auto power on is now enabled and good to go.

### Troubleshooting <a href="#troubleshooting-2" id="troubleshooting-2"></a>

For increased reliability on systems with the optional 4X4-V2000M CPU, it is recommended to disable the Core Performance Boost BIOS setting. To disable the setting, navigate to:\
Advanced -> CPU Configuration -> Core Performance Boost -> Set to “Disabled”

Press F10 to Save & Exit.
